Harris XM-100F 44pin pin out

[LostSignal]

Hi everyone. I am needing the pin out for the 44pin accessory port on the back of the radio? I would really appreciate the help in finding this out so I can interface to the following:

1) filtered audio (fixed level, hopefully in the range of 300mVpp to 600mVpp... usually a typical range for filtered audio... from my personal experiences)

2) MIC audio

3) PTT

4) finally, the return signal pins for both the audio and PTT (NOTE: I know that some radios have dedicated return signal pins for analog and digital signals)

Again, all the above is for the 44pin accessory port on the back of the radio. Thank you very much for helping.

Filtered audio will be pin 14 for signal, pin 1 ground.

MIC audio can be tricky, if its front mount use pin 12 for signal, 13 for ground. Remote mount uses Pin 27 for signal and 13 for ground.

PTT input is either an I/O pin (P18 for Inp1, P25 for Inp2) or Pin 29 to ground. P7 is a good general ground


Hope that helps!

Thank you for your input and I will try this. It might be a week or two before I get any results because of install issues at the moment. I will let you know how it went... just to let you know. Thank you again.
